March 21, 1929, Serial No. 348,935, and in Great Britain April 24, 1928.

prising in combination an arched casing, the

upper face of which constitutes one face of in; means (e. g. a detachable heating lamp) adapted to be received under the casing in a position to heat the upper portion of the arch, an abutment member carried by said casing I and situated opposite to, but spaced away from, the upper face of the casing, a presser member having a face opposed to the upper face of the arch, a screwthreaded press rod carried (e. pivotall; by the presser member), and a nut movable on the press rod between the abutment and the presser member and adapted to co-act with said abutment for forcing the presser member towards the upper face of the arch to clamp the article to be vulcanized.

According to another feature of the invention, the said abutment member is in the form of a bar having between its ends a hole into which the press rod extends, which bar constitutes part of an inv ertedU-shaped yoke mounted on the casing.

Preferably the abutment member constitutes a detachable part of the yokewhich is preferably detachably mounted on the cas- For a better understanding of these and other features of the present invention two embodiments thereof will now be described by way of example only, with reference to the accompanying drawings, in which:

Figure 1 is a perspective View showing one construction of the vulcanizer,

Figure 2 is a fragmentary view of a. detail of the vulcanizer shown in Figure 1,

Figures 3 and 4 showthe lamp of the vulcanizer in perspective and in section respectively, and

Figure 5 is a perspective view showing a canizer comprises a main rectangular casing in the form of an arch which maybe a pressing or a single casting, for example of aluminium; the casing is open at the bottom and has sloping front and back walls 11 and two side walls 12, which walls are closed by a top plate 13. The front and backwalls are continuous from the top to the bottom, but the side walls are cut away at let to permit of the insertion of a lamp 15 under the casing and to admit air to support combustion. The front and back walls have outwardly extending flanges 23 which have perforations for the reception of screws whereby the vulcanizer may be secured in position on a table or the like. The lamp 15 is received to slide on shelves 16, which are provided inside the casing on the inner faces of the front and rear walls 11 thereof. These shelves extend from the outside of one side wall to about the middle of the length of the vulcanizcr where they terminate inupwardly extending abutments 17 Immediately adjacent the abutments the shelves areformed with recesses 18. The lamp is provided with a handle 19 and with two projections 20 formed on its under surface towards its sides, which projections are adapted to interlock with the recesses aforesaid when the lamp is in its operative position. This is, forthepurpose of resisting endwise displacement of the lamp along the shelves but the arrangement is such that an illustrated in Figure 1.

recess 21 to receive the combustible. The recess has an inwardly directed flange 22 around it adjacent to and below the top of the lamp and the material of the lamp between the flange and the top is undercut. When liquid such as methylated spirit is being burnt this arrangement will be found to preclude the fuel from spreading over the upper surface of the lamp when alight and thus dissipating the heat and giving risk of fire.

Two upstanding supports 24 are mounted on the top plate 13 of the casing. The lower end 25 of each support is bent so as to extend at right angles to the general direction of the support and the ends 25 are each formed with a key hole slot 26 for engagement with a headed pin 27 projecting downwardly from the lower face of the top plate 13 (see Figure Towards its upper end each support is formed with an open ended slot 28. These supports are similar to one another and the slots 28 extend to corresponding edges of both of them. It follows, therefore, that, when the supports are mounted on the casing as shown in Figure 1 so that they face one another, the slots 28 are facing in opposite directions and preferably, for a reason to be explained later, they face in the directions The two supports carry an abutment member in the form of a bar 29 which is formed with a central hole 30 and with two recesses 31 one at each end, the recesses 31 being on opposite sides of the bar. The recessed ends of the bar are e.- gagedin the slots 28 on the supports which serve to carry the bar spaced away from and parallel to the top plate of the casing. It will be appreciated that instead of providing recesses 31 at the end of the bar two transverse slots may be provided, one at each end, the slots opening in opposite directions.

Extending through the hole in the bar 29 is a screwed rod 32 having its hea d 2-5? above the bar and carrying a wing nut 34 on that portion of its length located below the bar. A presser plate is screwed on to the end of the rod 32 by means of a ipcd boss secured to it. The under sui i re or ser member lies. in the operative 330 on of the latter, opposite the upper surface of the top plate of the casing. These two o 'ipoaed faces constitute clamping faces between which the vulcanizing operation is performed.

In operation. the supports-1 are mounted on the casing, the article to be vulcanized is placed on the top plate 13 and the abutment member is mounted on the supports. The wing nut 34 is then rotated in a counterclockwise direction as seen from above so as to force the presser member away from the abutment towards the casing so clamping the article between the presser member and the top plate of the casing. It will be seen that 'in opposite directions.

since the wing nut 34: is engaged with the abutment member 29 it will tend to turn the latter with .it in a counter-clockwise direction and will tend to force its ends into the slots 28 owing to the disposition of the slots pointed out above. The correct amount of combustible for providing the amount of heat required for one vulcanizing operation is placed in the recess in the lamp.

lVhen spirit is used there is provided a spirit measure which contains just but no more than this amount of spirit, and when solid fuel is used it is provided in pieces of exactly the correct dimensions for providing this amount of heat. The combustible is lit and the lamp placed in position under the using. The vulcanizing operation will be complete when the comlmstible has been entirely consumed.

lVhen the vulcanizer is to be of small size for example intended for vulcanizing cycle or motor-cycle tyres the spirit lamp 15 and the shelves 16 may be omitted. lVith such a vulcanizer the lid of the tin which contains the solid fuel may be used to support the fuel under the casing.

Referring, now to Figure 5, the construction of the casing and the lamp are as described. above, except that the casing is much longer and that it is formed with two holes 37 one at each end. The supports 38 are in the form of square rods with short screwthreaded portions 39 and 40 of reduced diameter one ateach end. Each support 38 is mounted on the casing with its screwthreaded portion 10 extending through one of the holes 37 and a nut 41 is provided on each support for holding it in position. The abutment member 29 is formed with a central longitudinal slot 12 and two transverse openended slots 43 one at each end and opening These slots engage the screw-threaded portions 39 of the supports and each of the latter carries a Wing nut- 44 whereby the abutment member may be clamped to the supports. It will be seen that the slots 43 enable the abutment member to be disengaged from the supports without the wing nuts l i having to be removed.

The presser member 35 has a screwed rod 45 pivotally secured to it at 46 and when in operative position lies opposite a flat boss f? on the top of the casing. The screwed rod carries a wing nut 34: and in its operative position its fre 2 end extends through the slot in the abutment member 29 and the Wing nut 34 below the latter. The operation of this vulcanizer is similar to the operation of the vulcanizer shown in Figure 1.

In a preferred process of patching punctured tubes or tyres employing the vulcanizer described above. the inner tube or tyre is patched with a rubber solution and with a rubber compound over the puncture and placed in vhe vulcanizcr. The solution and As the vulcanizer-cools the wax hardens and becomes joined to the material of the tyre or tube under the pressure exerted by the vulcanizer which acts as a press. In the case of a tyre a backing of canvas is provided which is joined to the material of the patch as the result of the pressure applied.

The vulcaniz-ers described above maybe made of aluminium and preferably have their exposed surfaces highly polished; Y It will be appreciated that the size of tyre which can be accommodated within the vulcanizer depends upon the distance between the su'pports and the particularc-onfiguration of these supports 24 shown in Figure 1 enables this dimension to be larger than the width of the casing, i. e., enables the casing tobe made of less width whilst still allowing of the same size of tyre being handled. it will be appreciated that various 'modifications may be made in the details of construction described above without departing from the invention. Thus, when the vulcanizer is intended for vulcanizing outer covers the presser members and the upper surface of the easing may both be curved to conform to the curvature of the'outer cover. V
